Mystery of the Pyramids Outdone. New York: Wellington Enterprises, ca. 2009. No matter which way the decorated canister is turned - right side up or upside down - the pyramid-shaped stack of graduated blocks inside stays right side up. Improved version of the U.F. Grant original. 7 ½" high. With instructions. Very good.
